From a precocious childhood passion for natural history to landmark contributions to coevolution, ecological speciation, biogeography, and botanical systematics, his career reshaped modern plant science. He was also an extraordinary mentor, collaborator, and institution builder spending most of his career as Director of the Missouri Botanical Garden and professor at Washington University in Saint Louis, while taking leadership roles at the National Academy of Sciences, the National Geographic Society, and many other organizations. Raven advanced global biodiversity conservation and scientific infrastructure and worked tirelessly to provide opportunities for emerging scholars worldwide. His legacy lies not only in the breadth of his scholarship and public service but also in his enduring commitment to connecting people, fostering collaboration, and helping others realize their potential.<\/jats:p>","DOI":"10.1073\/pnas.2624553123","type":"journal-article","created":{"date-parts":[[2026,8,19]],"date-time":"2026-08-19T17:37:08Z","timestamp":1787161028000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":0,"title":["Peter H.
